In a screen display device using an in-line color television picture tube provided with three electron guns, it is necessary to focus three electron beams generated from the three electron guns on the screen surface. For this reason, the conventional convergence method uses a self-convergence type deflection yoke. The self-converging type deflection yoke generally includes a pair of upper and lower saddle-type horizontal deflection coils and a pair of right and left saddle-type vertical deflection coils to achieve the desired convergence performance. However, when the deflection yoke is mass-produced, a practical problem occurs, and a convergence error may occur due to the dispersion of the performance of the mass-produced saddle-type coil. To correct such convergence errors, proper adjustment is performed by attaching a magnetic block to the proper position of the coil or using a correction circuit. Figures 13A and 13B show typical convergence errors caused by dispersion of the horizontal deflection field. Figure 1 A shows the pin-cushion type convergence error of the X (that is, horizontal) axis. When the pin cushion phenomenon (pmcnshmn) of the horizontal deflection field is too strong, a pin cushion type convergence error occurs. Figure 1 3B is a barrel-type convergence error on the X axis, which is found when the pin cushion phenomenon in the horizontal deflection field is too weak. In Figs. 13A and 13B, each solid line represents a red vertical bright line, and each dotted line represents a blue vertical bright line. Convergence errors shown in Figures 1 A and 1 B are generally referred to as "X Η Convergence errors j ° Unexamined Japanese Patent Application Publication No. 2-2 1 5 0 3 1 C.

1 2 6 series can slide in the direction indicated by the arrow to adjust the XH convergence error. As described above, the variable inductance coil 12 of the present invention includes a first magnetic core (for example, a cylindrical magnetic core 1 2 4) installed in the hollow space 1 2 1 e of the winding portion 1 2 1 b. In addition, the variable inductance coil 12 of the present invention includes a second magnetic core having an end surface area "S" larger than the end surface 1 2 4a of the cylindrical magnetic core 12 2 4. The first magnetic core and the second magnetic core may be integrated into one body or formed separately. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the notes on the back before filling this page) According to the configuration shown in Figure 7, the cylindrical core 1 2 4 is formed independently of the disc core 1 2 5 Separate components. When the cylindrical magnetic core 1 2 4 approaches the disc-shaped magnetic core 1 2 5, the gradient in which the inductance 增加 L increases becomes larger. The X Η convergence error correction is performed by shifting the cylindrical magnetic core 1 24 in the hollow space 1 2 1 e. If the inductance 値 L increases a very large gradient, it may complicate the adjustment of X Η convergence error correction. In this case, it is preferable to place the disc-shaped magnetic core 1 2 5 away from the end of the winding portion 1 2 1 b to increase the cylindrical magnetic core 1 2 4 and the disc-shaped magnetic core 1 2 5 Between the shortest moments away. Alternatively, it is preferable to separate the cylindrical magnetic core 1 2 4 from the disk-shaped magnetic core 1 2 5 by the wall 1 2 1 c 1 of the disk-shaped magnetic core holding portion 121c as described in the above embodiment. Conversely, it may be necessary to increase the increase gradient of the inductance 値 L. In this case, it is preferable to omit the wall 1 2 1 c 1 of the disc-shaped magnetic core holding portion 1 2 1 c. Alternatively, it is preferable to provide a perforation on the wall 1 2 1 c 1, and a cylindrical magnetic core 1 2 4 is inserted into the perforation to shorten the cylindrical magnetic core 1 2 4 23 This paper is applicable to China & quasi (CNS) A4 Specifications (210 X 297 mm) 409266 V. Description of the invention (>) The wrong conventional deflection yoke 3 is shown in Figure 14 'This conventional deflection yoke consists of the main coil 1 a and the auxiliary coil 1 b Horizontal deflection coil 1. The auxiliary coil 1 b functions as a winding leading portion or a winding end portion of the main coil 1 a. A variable inductance coil 2 is connected in parallel with the auxiliary coil 1 b. This configuration requires an intermediate tap 3 provided in the horizontal deflection coil 1. According to this configuration, the variable electric coil 2 functions as a bypass circuit and has the ability to control the horizontal deflection current flowing through the auxiliary coil 1 b connected in parallel with the variable voltage coil 2. This makes it possible to adjust the magnetic field generated in the horizontal deflection coil. With this configuration *, it is possible to correct the X Η convergence error shown in Figs. 13A and 13B. Figure 15 is a plan view showing the deflection yoke as seen from the electron beam exit (i.e., larger aperture) side. A funnel or bell-shaped splitter 4 houses a pair of upper and lower horizontal deflection coils 1 along its inner surface. Each horizontal deflection coil 1 is formed into a saddle shape having a window 5. The upper and lower horizontal deflection coils 1 are opposed to each other via a bundling portion 6. The auxiliary line 圏 1 b shown in FIG. 14 may be disposed in the area A adjacent to the window 5 corresponding to the inner peripheral portion of the horizontal deflection coil 1 shown in FIG. 15 to reduce the horizontal deflection current in the area A. . This configuration enhances the pin cushion effect of the horizontal deflection field. This makes it possible to correct the barrel-type convergence error shown in Fig. 13B. However, controlling the current in a limited area adjacent to window 5 may cause a difference between the convergence change in the X-axis of the screen and the convergence change in the corners of the screen.

According to the above-mentioned embodiment, the auxiliary deflection yoke 11 is provided at an appropriate position in the middle portion of the corresponding horizontal deflection line 圏 10, so that Convergence errors shown in Figure 16 can be ruled out. As apparent from the above description, X X convergence errors can be properly corrected. The connection between the horizontal deflection coil 10 and the auxiliary deflection coil 11 is not limited to the one shown in FIG. The mechanism for controlling the current flowing through the auxiliary deflection yoke 11 is not limited to the variable electric wire 圏 12. Hereinafter, the horizontal winding portion 20 will be described in more detail. When the horizontal deflection coil 10 is wound by a winder (not shown), the winding operation usually starts from the inner peripheral end of the adjacent window 15. The winding operation of the horizontal deflection coil 10 is performed from the inner peripheral end toward the outer peripheral end of the adjacent window 15. During this winding operation, the auxiliary deflection yoke 11 is combined with the water deflection coil 10 in an intermediate region between the inner peripheral end and the outer peripheral end of the adjacent window 15. Fig. 5 shows a horizontal winding portion 20 obtained by winding the horizontal deflection line 圏 10 and the auxiliary deflection coil 11 by the above formula.

The switching point of the single winding operation of the deflection line 圏 10 to the composite winding operation using both the horizontal deflection coil 10 and the auxiliary deflection coil 11 is interrupted. According to the above embodiment, the auxiliary deflection coil 11 is connected to the corresponding horizontal deflection. Line 圏 10 is rolled up or at the same time. However, when winding the auxiliary deflection line 圏 1 ', it is also preferable to stop the roll of the horizontal deflection line 圏 1〇. Operation. In this case, the 'auxiliary deflection coil 11' is wound independently of the horizontal deflection coil 圏 10. After the independent winding operation of the auxiliary deflection coil 11 is completed, the winding operation of the horizontal deflection coil 圏 10 is performed. In any case, during the winding operation of the horizontal winding section 20, the auxiliary deflection coil 11 is wound in the middle area of the horizontal winding section 20. In short, except for the horizontal deflection coil, The auxiliary deflection coil 11 is wound outside. However, the winding method of the auxiliary deflection coil 11 is not limited to the simultaneous winding method. In this method, both the horizontal deflection coil 圏 and the auxiliary deflection coil are wound simultaneously. The invention can apply all winding methods, in which the auxiliary deflection coil 11 is wound in the middle stage of the winding operation of the horizontal deflection coil 10. The auxiliary deflection coil 11 can be configured to be adjacent to the horizontal deflection closer to the separator 14 The surface of the coil 10, or the surface disposed adjacent to the horizontal deflection line 010 which is far from the separator 14. Alternatively, the auxiliary deflection coil 11 may be disposed in the internal space of the horizontal deflection coil 10.

Description of the invention () As shown in Fig. 5, the horizontal winding section 20 has A total of four extension lines. Among the four extension lines * two extension lines 1 0 a are winding lead portions and winding end portions provided at the horizontal deflection coil 10 and two extension lines 1 1 a are winding lead portions provided at the auxiliary deflection coil i 1 Section and winding terminal section. The winding operation of the horizontal winding section 20 can be automatically performed by the winding machine. There is no need to provide an intermediate tap for the horizontal deflection coil 10. The two additional extension lines will not complicate the assembly of the deflection yoke. "As described earlier, the deflection yoke of the present invention includes an auxiliary deflection line 圏 11 in addition to the horizontal deflection yoke 10 for winding. When both the auxiliary deflection coil 11 and the horizontal deflection coil 10 are made of the same electric wire, it becomes difficult to distinguish each other.
